<span class="sourceLineNo">044</span> * released when the associated Stream is garbage-collected. It is not a good<a name="line.44"></a>
<span class="sourceLineNo">045</span> * idea to rely on this mechanism. For a good overview of the distinction<a name="line.45"></a>
<span class="sourceLineNo">046</span> * between "memory management" and "resource management", see<a name="line.46"></a>

<span class="sourceLineNo">050</span> * For byte-to-char methods, a {@code copy} variant allows the encoding<a name="line.50"></a>
<span class="sourceLineNo">051</span> * to be selected (otherwise the platform default is used). We would like to<a name="line.51"></a>
<span class="sourceLineNo">052</span> * encourage you to always specify the encoding because relying on the platform<a name="line.52"></a>
<span class="sourceLineNo">053</span> * default can lead to unexpected results.<a name="line.53"></a>
<span class="sourceLineNo">054</span> * &lt;p&gt;<a name="line.54"></a>
<span class="sourceLineNo">055</span> * We don't provide special variants for the {@code copy} methods that<a name="line.55"></a>
<span class="sourceLineNo">056</span> * let you specify the buffer size because in modern VMs the impact on speed<a name="line.56"></a>
<span class="sourceLineNo">057</span> * seems to be minimal. We're using a default buffer size of 4 KB.<a name="line.57"></a>
<span class="sourceLineNo">058</span> * &lt;p&gt;<a name="line.58"></a>
<span class="sourceLineNo">059</span> * The {@code copy} methods use an internal buffer when copying. It is<a name="line.59"></a>
<span class="sourceLineNo">060</span> * therefore advisable &lt;em&gt;not&lt;/em&gt; to deliberately wrap the stream arguments<a name="line.60"></a>
<span class="sourceLineNo">061</span> * to the {@code copy} methods in {@code Buffered*} streams. For<a name="line.61"></a>
<span class="sourceLineNo">062</span> * example, don't do the following:<a name="line.62"></a>
<span class="sourceLineNo">063</span> * &lt;pre&gt;<a name="line.63"></a>
<span class="sourceLineNo">064</span> *  copy( new BufferedInputStream( in ), new BufferedOutputStream( out ) );<a name="line.64"></a>
<span class="sourceLineNo">065</span> *  &lt;/pre&gt;<a name="line.65"></a>
<span class="sourceLineNo">066</span> * The rationale is as follows:<a name="line.66"></a>
<span class="sourceLineNo">067</span> * &lt;p&gt;<a name="line.67"></a>
<span class="sourceLineNo">068</span> * Imagine that an InputStream's read() is a very expensive operation, which<a name="line.68"></a>
<span class="sourceLineNo">069</span> * would usually suggest wrapping in a BufferedInputStream. The<a name="line.69"></a>
<span class="sourceLineNo">070</span> * BufferedInputStream works by issuing infrequent<a name="line.70"></a>
<span class="sourceLineNo">071</span> * {@link java.io.InputStream#read(byte[] b, int off, int len)} requests on the<a name="line.71"></a>
<span class="sourceLineNo">072</span> * underlying InputStream, to fill an internal buffer, from which further<a name="line.72"></a>
<span class="sourceLineNo">073</span> * {@code read} requests can inexpensively get their data (until the buffer<a name="line.73"></a>
<span class="sourceLineNo">074</span> * runs out).<a name="line.74"></a>
<span class="sourceLineNo">075</span> * &lt;p&gt;<a name="line.75"></a>
<span class="sourceLineNo">076</span> * However, the {@code copy} methods do the same thing, keeping an<a name="line.76"></a>
<span class="sourceLineNo">077</span> * internal buffer, populated by<a name="line.77"></a>
<span class="sourceLineNo">078</span> * {@link InputStream#read(byte[] b, int off, int len)} requests. Having two<a name="line.78"></a>
<span class="sourceLineNo">079</span> * buffers (or three if the destination stream is also buffered) is pointless,<a name="line.79"></a>
<span class="sourceLineNo">080</span> * and the unnecessary buffer management hurts performance slightly (about 3%,<a name="line.80"></a>
<span class="sourceLineNo">081</span> * according to some simple experiments).<a name="line.81"></a>
